Abstract

Education for the 21st century combines knowledge, abilities, and attitudes with a command of information and communication technologies. The role of education is very important as part of an effort to build national character and produce millennials who are innovative, creative, and ready to face global challenges. 21st-century skills are one of the skills that students must have to face global challenges. 21st century skills include critical thinking, creativity, collaboration, and communication, otherwise known as "4C skills." 21st-century skills are also very much needed in learning physics. One of the best teaching materials for enhancing students' 21st-century skills is an e-module built on the inquiry model and the science, environment, technology, and society (SETS) approach. The goal of this study was to establish the validity, practicability, and efficacy of e-modules created using the SETS approach integrated inquiry model in increasing students' 21st century competencies. This type of research is called development research (RD). This development procedure refers to the Plomp development model, which has three stages: preliminary research, prototyping, and assessment. E-module validation is reviewed from four aspects: the substance of the material, the learning design, the appearance, and the use of the software. The average score obtained for the substance component of the material, the learning design, the appearance, and the use of the software is in a very valid category. Based on these data, it can be concluded that the inquiry model-based e-module integrated with the SETS approach is in the "very valid" category

Abstract

Diabetes melitus merupakan gangguang kesehatan global yang menjadi perhatian penting untuk menemukan pencegahan dan terapi baru. Diabetes melitus dapat diobati menggunakan obat golongan inkreitin untuk menghambat kerja enzim DPP-4. Daun yakon (Smallanthus sonchifolius) merupakan tanaman herbal yang sering digunakan untuk mengobati berbagai penyakit dan diketahui memiliki turunan senyawa sekunder baru. Tujuan penelitian ini adalah mengetahui aktivitas senyawa baru daun yakon menginhibisi enzim DPP-4 berdasarkan energi dan ikatan kimia secara in silico. Senyawa baru daun yakon adalah turunan asam octadecatrienoic dan Benzyl glikosida. Senyawa tersebut diambil dari pubchem dan digambarkan kembali menggunakan chemdraw, sedangkan enzim DPP-4 (reseptor) didapat dari bank protein dunia dengan kode PDB ID: 3F8S. Penelitian ini dilakukan dengan metode In Silico dan perangkat lunak AutoDock Vina digunakan untuk proses penambatan. Hasil optimasi gridbox dengan melakukan penambatan ulang ligan kontrol diperoleh hasil RMSD sebesar 1.628 Å. Hasil penambatan molekuler dapat disimpulkan bahwa senyawa baru daun yakon berpotensi menghambat aktivitas enzim DPP-4 sebagai antidiabetes berdasarkan nilai energi bebas ΔG dan ikatan kimia. Interaksi yang terbentuk antara ligan dan reseptor tepat pada sisi aktif enzim DPP-4 yaitu Glu205, Glu206, Asn710, Tyr662, Arg125, Ser630, Phe357, Tyr666, Tyr547 dan Ser209. Interaksi yang terjadi antara ligan dan reseptor didominasi oleh ikatan hidrogen. Senyawa 13(R)-hydroxyoctadeca-(9E,11E,15Z)-trienoic acid (ligan 1), benzyl +alcohol 7-O-α-L-arabinopyranosyl-(1"→2')-β-D-glucopyranoside (ligan 2), 13(R)-Hydroxy-octadeca-(9Z,11E,15Z)-trienoic acid (ligan 3) memiliki nilai ΔG sebesar -6.2 kkal/mol, -7.7 kkal/mol dan -5.6 kkal/mol. Namun, Benzyl alcohol 7-O-α-L-arabinopyranosyl (1"→2')-β-D-glucopyranoside (ligan 2) lebih berpotensi menghambat enzim DPP-4 karena nilai energi bebas Gibbs (ΔG) dan ikatan kimia yang terbentuk lebih negatif dan stabil dibandingkan ligan 1 dan 3
